DUST ARRESTER AND SLUDGER.

Application filed January 26, 1907. Serial No. :354,222.

To aZZ whom it may concerns Be t known that we, Loris THEODORE SICKA and J oHx PHILIPCOL INS, both citizens of the United States, and residents of the city of Butte, County of Silver Bow, and State of Montana, have invented certain new and useful Improvements in Dust-Arresters and Sludgers, of which the following is a specificatio'n.

This invention relates to drills, and it has particular reference to an apparatus for removing the cuttings or borings from the tool without. removing the drill.

The object of the invention is to provide novel means for utilizing a portion of the drill Operating power for t'orcing a stream of water into the. cavity formed by the drill and in washing therefrom the borings or cuttings,

which would otherwise impede the operation of the drill, the water so used also serving to 'prevent excessive high temperature of the drill.

Figure l represents a side View partlv in g section of a system of rock drilling machinerv embodying our invention. Fig. 2 is a side view partly in section of the water tank with connections. Fig. 3 is a top View of the water tank. Fig. 4 and Fig. 5 are detail views of frame tor supporting the water tank.

Beterring to the drawings A. is a drilling machine which is suitably sup orted o v the column B the ends of whic 1 are placed against the' blocks C the column B being adjusted by means of the screw D.

The drilling machine A' is operated by means of compressed air,- steam, 'or gas which is supplied through the flexible hose E and is admitted to the drilling machine A by means of the valve F.

To the end of the reciprocating piston G the shank H of the drill bit I is'inserted in the chuck J. The other end of the drill bit I is enlarged as at K and as the bit I is reciprocated and revolved simultaneously by the mechanism of the drilling machine A a hole L is bored by the bit I which has a uni- Specification of Letters Patent.

are not easily removed from the hole. The dust and bits of rock fill the hole and wedge the drill in such a manner that it 'does not work easily and the end of'thedrill instead of cutting the solid rock at the bottom of the hole continues to cut these bit's "of 'ock'into smaller pieces thus iuterfering with the economical working of the drill. To obviatc .these disadvantages I have provided a water tank N preterably madeof steel which is formed in thisinstance with' ar funnel shaoed top o to tacilitate the tenk N being filled with water. The top 'of the tank is closed and made air tight by means of the detachable plug P. At the top of the'tank N extending out through the side is a holeQ in which a suitable pipe R provided 'with a valve S is Secured. v

At the bottom ot the tank N extending out` through the side is a hole T in which a suitable 1pipe U, provided with a valve V is secure( in the same manner as the pipe R is'secured in the hole Q at the top of the tank N.

T o the pipe R a suitable connection' is made with a fiexible hose W said. hose being attached. at the other end to the aii' su'pp'ly hose E by means of the tee connection' X below which a suitable valve Y is provided to turn otl' or on the air pressure supplied through the 'llexible pipe E. When the compressed air is turned on by opening the valves Yand S pressure is exerted on top ot the water in the tank N thus torcing the wateroutthrough the bot-tom of the tank N through the hol jT; and the pi pe. U out through the tlexible pipe Z to the metal nozzle a.

The metal nozzle a can 'be' m ade any desired length but is preferablymade nearly the len th of the drill bit I The hole l) at the disc liarge end of the nozzle 'a ismadecomparatively small to increase the velocityof the water as it leaves the nozzle. To facilitate cleaning, the nozzle aas referably se-, cured at right angles to the' flexble hose -Z by means `of a' tee connection c which has aremovable plug d which When removed permits the easy insertion ofa Wire or* ro'd for the purpose of 'emov'irig any dirt thatmay collect inside the nozzle a; Belowthetee icon- 5 n ection c, a va-lve eis providedfor regultng the amount of Water passing through 'the nozzle a.

The Water tenk N is made withan internally rounded' top f and bottom g as 'shown for the 'purpose of using all the available shown in Fig. 1

water in the tank when the tank is set on an uneven surface.

The tank N is preferably supported upon the frame h by means of the handles y' which are rigidly attached to the tank N and rest on to of the frame h in the grooves k.

%he frame Y is preferably made of steel and constructed out of one iece of sheet metal which affords a very simp e and effective device for supporting the water tank M always in a vertical direction so as to permit the use of all the' water contained n the water tank N when the surface upon which the frame h rests is uneven.`

The o eration of the device is as follows: The drilliig mac-hine A is first put in position as shown in Fig. 1 and is then operated by the compressed airwhich is supplied through the hose E and regulated by means of the valve F which turns the compressed air on or off as desired. The water tank N is then .filled with water by removin the plug P which is again inserted after filling the tank, The hose W' leadin to the top of the water tank N is then made fast by proper connections to the tecX on the supply hose E. The valve Y in the hose TV is then opened and the air under pressure passes from the hose E through the hose `W to the surface of the water in'the t-o of the tank N. The pressure thusexerte forces the water out through the bottom of the tank N through the hose K to the nozzle a. The nozzle a is then inserted in the hole L made by the drill as The water as it passes into the end of the drill hole under pressure keeps the hole and drill free and clear of all bits of rock and dust, 'and' permits the drill to work without stop ping for the purpose of cleaning the drill holes.

The ap aratus works entirely independent of the dri ling machine A and injeets a continuous stream of water under pressure' at the oint it is most needed and can be operatec Very easily by either the operator or his helper.

The motive ower is consumed merely to the extent of te amount of water displaced in the tank N.

By inject-ing water under pressure to the bottom of the drill hole all dust is prevent-ed thus obviating all the disagreeable efl'ects resulting therefrom upon the health of the operator. I .T he water tank may be placed in any convenient position out of the way of the operator, and is so constructed, that the uneven surface of the ground upon which it may rest, does not interfere with the tank assuming an u right osition, which is necessary to utilize a l of the water placed in the tank The wat-er tank may be placed either above or below the level of the hole to be drilled and works equally well in either osition.

The water tank is constructe in the simlest possible .nanner and in no way intereres with the operation of the drilling machine. The water tank can be easily cleaned together withall its attachments especially the nozzle a whi'ch is Secured to the pi e Z in such a manner that it can Very rea( ily be cleaned when it becomes clogged with small bits of rock or other substance.

What we claim is:

1. In a rock drilling system, an air supply, an air operated rock drillng machine, a drill bit enlarged at the cutting end and operated by said drilling machine, a water tank, the top of which is flexibly connected' to the air supply, a nozzle flexibl connected to the bottom of said Water tan and adapted to be inserted in the drill hole. behind the enlarged end of the drill bit, means for regulating the air pressure in the water tank, means for regu ating the water discharged at the cutting end of the drill bit, said water tank being provided with an internally concaved lower end for utilizing all the water in the tank.

; 2. In a rock drilling system, an air sup ly, an air operated .rock drilling machine, a drill bit enlarged at the cutting end, a water tank, the top of which is flexibly connected to the air sup ly, a tubular nozzle flexibly connected to t e bottom of 'said water tank and of small size so as to be inserted in the drill hole behind the enlarged end of the drill bit, means for regulating the air pressure in the water tank; means for regulating the water discharged at the cutting end of the drill bit, and means for utilizing all the water in the tank. i

3. In a rock drilling system, an air sup ly, an air operated rock drilling machine, a rill bit enlarged at the cutting end, a water tank, the top of which is flexibly connected to 'the air supply, a tubular nozzle flexibly connected to the bottom of'said Water tank and of small size so as tobe inserted in the drill hole behind the enlarged end of the drill bit, means for regulatingthe air pres'sure in the water tank, means for 'regulating the water discharged at the cutting end of the drill bit,
